Definitions

  • liquid alkaline, hypochlorite compositions are commonly employed in such applications.
  • Such compositions generally contain strong alkali, suitably, potassium or sodium hydroxide, in the range of 5 to 15% to saponify fats; sodium or potassium hypochlorite at levels providing 1.5 to 4% available chlorine to break down protein; and suitable levels of various hypochlorite stable chelating and/or sequestering agents to tie up the water hardness minerals at the desired product usage level.
  • the concentration of the products of this type is diluted with water at ratios of between about 1:320 (1 oz. cleaner to 5 gallons of water) to about 1:40 (1.5 oz. cleaner per gallon water).
  • Most of these compositions result in satisfactory cleaning results provided the mechanical effect, temperature, and time of the wash cycle is sufficient.
  • the current art of alkaline hypochlorite cleaners do not provide satisfactory results.
  • U.S. 4,740,327 describes a thixotropic dishwasher formulation which includes chlorine bleach, a diphenyloxide disulfonate surfactant and a foam depressant such as an alkyl phosphonic or phosphate acid ester or "silicones and etc.”.
  • surfactants present in this new composition, one being a high foaming sulfonate surfactant, the other being a nonionic surfactant which functions as a defoamer at temperatures above its cloud point.
  • the alkylated diphenyloxide sulfonate surfactant is selected from compounds in which the alkyl groups are C 4 -C 8 alkyl groups, suitably C 6 alkyl groups. Most preferably this compound is a dialkyl diphenyloxide disulfonate. Such compounds are sold under the Dowfax trademark by Dow Chemical Company. In particular, Dowfax XDS 8292.00, a dialkyl diphenyloxide sulfonate in which the alkyl groups are linear 6-carbon groups has been found to be a suitable sulfonate surfactant in the formulations of the invention.
  • the useful levels of the surfactant compounds are significantly restricted by the need to maintain available chlorine and to suppress foam.
  • the diphenyloxide sulfonate component provides good stability in alkaline hypochlorite and very good cleaning performance but unacceptable foaming behavior. If foam suppression is accomplished using excessively high levels of nonionic surfactant, hypochlorite stability is poor. At ratios of sulfonate/nonionic surfactant between 2.5:1 and 3.5:1 acceptable foam suppression and hypochlorite stability can be achieved. Most preferably the ratio of sulfonate to nonionic surfactant is about 3:1.
  • nonionic surfactants are selected from those which will form clear solutions at 120oF when incorporated into the formulations of the invention at the levels specified above.
  • Preferred nonionic surfactants are sold under the trademarks Plurafac RA and Macol by BASF Wyandotte Corp. and PPG/Mazer Corp., respectively.
  • the compounds sold under Plurafac RA-40 and Macol 21 give formulations with acceptable foam levels for clean-in-place dairy milking systems when compounded with the remaining ingredients of the formulation in the ratios previously stated.
  • Example 1 The results in Table 1 demonstrate that the 4:1 ratio caused such high foam levels that the C.I.P. system had to be shut down. This was also true for the control with only sulfonate surfactant, no defoamer. It also illustrates that at ratio's of 2.5:1 and 3:1 the amount of surfactant to achieve controlled foam expressed as a percent of the dairy detergent (surfactant being added to wash solution and not part of composition) should be less than about 2% of the formula.
  • Example II The objective of this example was to select a defoaming nonionic surfactant which would be solubilized by the sulfonate surfactant into a detergent formula 1 such as listed in Example I.
  • Example III The dialkyl diphenyloxide disulfonate surfactants Dowfax 2A1, 3B2, XDS 8292.00, and XDS 8393.00 were compared as solubilizing agents for Macol 21 in the detergent formulation given in example I.
  • the formula was 98.275% of the detergent formula, 0.225% Macol 21, and one of the Dowfax surfactants at 1.50%.
  • the Dowfax surfactant and Macol 21 were premixed before addition to the alkaline, chlorinated detergent. Solutions with Dowfax 2A1, 3B2, or XDS 8393.00 were insoluble. The solution with Dowfax XDS 8292.00 was clear.
  • Example IV A series of alkaline, chlorinated C.I.P.
  • RATIO SULFONATE TO - 2.5:1 2.75:1 3:1 2:1 2.75:1 - 2.5:1 2.75:1 3:1 2:1 2.75:1 NONIONIC SURFACTANT
  • compositions E, F, and L exhibited poor hypochlorite stability.
  • Composition K was insoluble.
  • Composition F which showed better stability than the other silicone samples, demonstrated extremely high foam in the C.I.P. system at 1 oz/2 gal. when tested as in example I. Insolubility and hypochlorite instability problems, as well as inadequate defoaming performance prevents the usage of this class of defoaming chemicals in this product type and its application.
  • compositions B, C and D showed increasing hypochlorite stability as the sulfonate to defoamer ratio increased.
  • Composition D has a commercially acceptable shelf life, not substantially lower than the control composition A. After 10 days at 50oC composition D has a %NaOCl retention of approximately 62%, whereas the control composition, without any surfactants, had a % NaOCl retention of approximately 69%. These results indicate that for storage for 10 days at 50oC, roughly equivalent to 6 months or greater at room temperature, the sulfonate surfactant shielded the defoaming nonionic surfactant from attack by the hypochlorite radical quite effectively.
  • Sample A and D were maintained in storage at 50oC were another 10 days. After 20 days at 50oC (equivalent roughly to greater than one year at room temperature) the % NaOCl retention of composition D was 25.0%, compared to 48.7% for the control sample A. Thus, only upon very extended storage do the hypochlorite stabilities diverge substantially.
  • compositions J at 46.5% NaOCl retention is closest in stability to the control composition G at 52.9% retention, but, the small increase in sodium hydroxide had as strong negative effect on stability for all formulations, indicating that compositions more concentrated than D are not preferred.
  • liquid alkaline chlorinated C.I.P. cleaners with acceptable shelf-life and controlled foam characteristics can be readily formulated within the scope of the claims appended hereto.

Abstract

Les préparations de nettoyage décrites sont appropriées pour le nettoyage sur place d'équipements dans lesquels circulent des produits alimentaires, tels que des produits laitiers. Ces préparations sont constituées par des compositions alcalines, qui contiennent une source de chlore disponible (de préférence de l'hypochlorite) et dans lesquelles est inclus un mélange d'agents tensioactifs, dont l'un est un sulfonate de diphényloxyde alkylé de 4 à 6 atomes de carbone et dont l'autre est un agent tensioactif non ionique, qui est stable dans la préparation dans certaines plages de concentration et qui agit de façon à supprimer le moussage.
